Research On Infared Technology For Coal Mine

In recent years,more and more attention to the safety and supervision of coal mines,and for Shanxi,the safety of coal mining industry is particularly important.Therefore,we must improve the level of management,and to ensure the safe and efficient production of coal mine,and for managers and operators,they need to know the real-time dynamic distribution of staff,the difference in the number of accurate,also need to sum up the special type of personnel tracking and other activities.Underground work environment and terrain is relatively poor,unable to track and check employee attendance,a lot of things are inevitable,do a good job in advance personnel,personnel positioning system can ensure the accuracy of the technology.At the same time,in the event of a dangerous or unexpected event,how can we find a timely and accurate personnel positioning becomes very important.Based on the analysis and comparison of the wireless communication technologies such as GPS,Bluetooth,ultra wide band,radio frequency identification,WLAN positioning,computer vision and so on,the infrared positioning technology is selected as the communication technology of the personnel positioning system.At the same time,in this paper,based on the AOA positioning algorithm,the precise positioning of reverse thinking.The positioning accuracy of the positioning algorithm is improved by the dynamic acquisition of environmental parameters.The extraction rate of the database and data storage capacity can reach the ideal state,my undergraduate studying computer science,the data compression has done some research,and improve the compression rate,the design andimplementation of an underground personnel positioning method,and through simulation experiments and simulation experiments verify the data compression the feasibility and follow-up to further research plan is discussed.
